VA P O R l 2 E R.

SPECIFICATION forming part of Letters Patent No. 397,631, dated February 12, 1889.

Application filed May 22, 1888. Serial No. 274,660. (No model.)

To all whom it may concern:

Be it known that I, ROBERT B. CARSLEY, of New Bedford, in the county of Bristol and State of Massachusetts, have invented an Im- 5 provement in Vaporizers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to provide apparatus in which gasoline and analogous hydrocarbons may be vaporized, and the va por, either alone or mixed with air or gas, be employed for lighting and heating purposes.

My invention in a vaporizer consists, essentially, of a vessel provided with a liquidinlet and a vaporoutlet, combined with a series of substantiallyvertical double partitions forming vapor ways, and arranged within said vessel to form chambers, absorbent material in said chambers, and a plate or wall to support said double partitions, the said plate or wall forming, with the bottom of the vessel, a vapor receiving chamber, sub

stantially as will be described.

The specific features of my invention will now be more fully pointed out, and claimed at the end of this specification.

Figure l is a front elevation of a vaporizer 3o embodying my invention, the front plate or side being removed, and only one chamber being shown full of absorbent material. Fig. 2 is a sectional plan view of the vaporizer on line a: 00, Fig. 1, with the supports or shelves for 3 5 the absorbent material omitted to avoid c011- fusion in the drawing. Fig. 3 is a section of the vaporizer on line cc at, Fig. 2. Fig 4 is a detail of one of the supports or shelves; and Fig. 5 is a vertical section, on a large scale,

of an'automatic valve, to be referred to.

The vessel A, preferably of tin, and which may be of any desired shape, being herein shown oblong, is divided into a series of chambers or spaces, a, by double partitions a, composed, preferably, of wire-netting or other foraminous material, bent or folded upon itself to form a vapor way or passage. The double partitions a are supported above the bottom of the vessel by a plate or wall, a

preferably of wire-netting, the said plate or wall forming, with the bottom of the vessel A,

a chamber, 17, communicating with the vapor ways or passages a, the vapor descending from the said ways or passages a into the chamber 19.

The chambers or spaces to contain asbestus or other absorbent material, b, which is preferably supported by detachable shelves 01' supports b (shown separately in Fig. 4,) there being preferably two or more superim- 6o posed shelves in each chamber, .as shown in Fig. 1, the said shelves preventing the absorbent material becoming matted or packed together when saturated with gasoline or analogous hydrocarbon to be vaporized.

The gasoline or analogous hydrocarbon is supplied through a suitable pipe, herein shown in the side of the vessel A, the said pipe being provided with a suitable cap, 12 the said vessel being turned on its side when it is to be filled, the liquid hydrocarbon preferably flowing from the pipe 6 upon a distributing plate, 19 preferably soldered or otherwise attached to one of the/double walls,

a, a more even distribution of the liquid hydrocarbon being thus obtained.

The double partitions a are preferably strengthened, as herein shown, by braces c, composed, preferably, of tin bent or shaped substantially as shown in Fig. 3 and soldered or otherwise fastened to the double partitions, the said braces being especially effective when the double partitions are made of wire-netting to prevent crushing together of the said partitions, thus maintaining the vapor ways -or passagesfrec and unobstructed.

The central chamber or space contains, as herein shown, an inverted trough or cap, 0 preferably extended the width of the vessel A, the said trough or cap being supported, as 0 shown, by the plate or wall (L The vapor generated in the vessel A is conveyed therefrom by a discharge-1.)ipe, (1, extended up into the trough or cap 0 and connected in practice to a burner-pipe, (not 5 shown,) the discharge-pipe being provided with a suitable cook or valve. (Not shown.)

The vessel A has secured to its top an automatic valve comprising a valve case or shell, cl, (see Figs. 1 and 5,) herein shown as provided with a conical base, which is soldered or otherwise secured to the top of the vessel,

thesa'id base forming the seat for a valve, (1 having its stem (1 extended through guides (l and threaded at its end to be engaged by a nut, (1 the said valve-stem being encircled between one of the guides d" and the nut d" by a coiled spring, (F, the tension of which may be regulated to just seat the valve dthat is, to substantially balance the said valve. The valve-shell is provided with a cap, (Z which covers the valve when the apparatus is being transported, but which is removed when the apparatus is set up in operative position.

In operation, the cock or valve in the discharge-pipe being closed,the vessel A is turned on its end and the gasoline admitted through the pipe 19 (the cap 1)" being removed) until the absorbent material has been saturated. The cap I) is then replaced and the vessel turned into operative position, (shown in Fig. 1,) and any excess or surplus liquid may be drawn oil" by the drip-cock e, if desired. The gasoline immediately begins to give off vapor, which passes intothe vapor ways or passages, and, being heavier than air, descends by grayity into the chamber b, from which it passes upinto the trough and out by the dischargepipe, the said trough being extended the width of the vessel, thus affording a greater head, as it were, and therebya better and freer flow of vapor to the burners when the cock in the discharge-pipe is opened. WV hen the absorbent material is saturated,the vapor generated in the vessel A exerts a pressure upon the valve (Z and assists to seat the same, thereby preventing escape of vapor from the vessel A. \Vhen the cock at the burner is opened, the pressure upon the valve is relieved, and the said valve is opened by atmospheric pressure, the air entering the vessel A and acting to eX- pelall or substantially all the vapor therein.

I have herein described my improved apparatus as a vaporizer; but it is evident it may also be used as a carburetor to enrich air or other gas which may be admitted into the said vessel through the valve, a suitable pipe connected to the gas-supply or to a reservoir containing compressed air, and not herein shown, being connected to the valveshell.

It will be noticed that the double partitions are secured in the vessel in a substantially vertical position to afford a free and unob structed passage for the vapor.

vapor-outlet, ofa' series of double partitions forming vapor-ways, and arranged within said vessel to form chambers, absorbent material in said chambers, a plate or wall to support said double partitions, and shelves b to support the absorbent material, substantially as described.

3. In a vaporizer, the eo1n l. ination, with a vessel provided with a liquid-inlet and a vaper-outlet, of a series of double partitions formin g vapor-ways, and arranged within said vessel to form chambers, absorbent material in said chambers, a plate or wall to support said double partitions, and shelves to support the absorbent material, and an inverted trough or cap located above the outlet-pipe ot' the vessel, substantially as described.

at. In a vaporizer, the combination,with avessel provided with a liquid-inlet and a vaporoutlet, of a series of double partitions forming vapor-ways, and arranged within said vessel to form chambers, absorbent material in said chambers, a plate or wall to support said double partitions, and shelves to support the absorbent material, and an inverted trough or cap located above the outlet-pipe of the vessel, and a check-valve secu red to the top of the vessel and adapted to open to admit air 9 to the vessel when the vapor is being withdrawn from the said vessel, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribingwitnesses.

R. B. CARSLEY.
